Description

Systemcore reports an input voltage of ~17.4 while a multimeter measures 19 at the input terminals (probes inserted into back of minifit connector). Motioncore also reports ~19v.

This is a beta unit running the beta-10 image.

Research direction

Start with the reported beta unit running the beta-10 image and reproduce the discrepancy between Systemcore's ~17.4 V reading and the multimeter's 19 V measurement at the input terminals. Compare the corresponding Motioncore reading of ~19 V and determine whether the Systemcore measurement is consistently inaccurate; done means the cause is identified and the reported voltage agrees with the reference measurement.
